This fusion reaction releases a tremendous amount of energy in a very short time, causing the accumulated surface layer to explode violently away from the dwarf. This fading occurs as the ejected material expands into space, cooling and dispersing, while the underlying white dwarf begins to accumulate fresh material once more.

When the pressure reaches a critical point, nuclear fusion is triggered in a thin shell around the core. Therefore, a nova is an event on a star, not the star's total demise.
A nova is a specific and dramatic event occurring on the surface of a white dwarf star, which is the dense, collapsed core of a once-normal star. While both are stellar explosions, their origins and outcomes are entirely different.

Supernova It is crucial to distinguish a nova from its more catastrophic cousin, the supernova. Astronomers observe the initial optical brightening, which can make the star suddenly visible in the night sky, sometimes outshining its entire host galaxy for a brief period.
